OWNER'S MANUAL

1. REPEATED LISTENING DESIGN SESSIONS:
Fine tuning of sound by exchanging and mixing of parts (transistors, capacitors, wiring, PCB boards
etc.), and adjusting many specific operating voltages within proper engineering ranges, producing an
overall sonic recipe giving the most natural harmonic realism of music typical of instruments in a
live performance.

2. UPGRADABLE SINGLE CIRCUIT DESIGNS:
All Classé products (all preamps and all amps) share exactly the same circuit design philosophy
(excluding moving coil and moving magnet phono circuits). This means all amplifiers and all high
level circuits of the preamps benefit from the same design goals. Similar circuits are then tailored to
different power levels etc. Differences between less expensive models and more expensive models
are parts quality and compliment, power supply extravagance and the amount of filtering etc., as
well as features and packaging.

This means that for years Classé has been constantly sonically fine tuning and technically upgrading
this circuit design and its application, thus reaching a very high level of natural musical enjoyment,
as well as excellent reliability which benefits all models - least expensive, most expensive, preamps
and amplifiers alike.

3. EXTREME LONG LIFE IN REAL WORLD CONDITIONS:
Choosing the best attainable quality parts and materials combined with the advantages of the two
above-mentioned areas provides Classé owners with years of proven trouble free reliability and
musical enjoyment.

TABLE OF CONTENTS

UNPACKING & SET-UP

Your new preamplifier has been carefully wrapped in heavy gauge plastic, packed in semi-rigid
foam and contained in a special box. To remove the unit, open and spread the top flaps of the box. By
its sides, lift out the entire unit with the foam pieces intact. Remove each foam side by pulling straight
out. Remove the plastic wrap and inspect the unit for any concealed damage. Apart from this owner's
manual, please ensure the following has also been included:

1) Detachable linecord

2) 5/64 in. Allen key for top cover

3) (PHONO MODEL) Resistor kit for Moving Coil gain adjustment.

4) (REMOTE CONTROL OPT. ONLY) Control unit. (Allen key and Batteries AAA X 3
included).
Please report any damage or missing parts to your dealer promptly.
This preamplifier, being capable of very high gain, must be located in a position free of any
hum-inducing magnetic fields. (This also applies to turntables and interconnect cables.) Positions
adjacent to power amplifiers, A.C. line filters, or regulation devices should be avoided. Ideally, a few
feet should separate the preamplifier from the power amplifier. As well, keep low-level interconnect
cables away from the power amp and separate from A.C. line cords.
Heat generated by the preamplifier is negligible. Air space around the unit need not be a
concern.
Check the Serial Number sticker on the back of the unit for the correct operating voltage.
Regardless of voltage, the fuse rating should be 1 AMP SLO-BLO.
